Synopsis

This unit provides part of a major in theoretical physics. It consists of two 12-lecture sub-units, Advanced Quantum Mechanics and Computational Physics and a 12-hour seminar sub-unit. The key areas of study are:

  1. Advanced Quantum Mechanics: spin angular momentum, perturbation theory, scattering theory and the quantum theory of radiation;
  2. Computational Physics: discrete arrays to model the space and time evolution of functions or physical systems; a hands-on approach is used throughout to develop confidence and competency in using a computer to solve physical problems; includes a computer based assignment and short computational physics project; and
  3. Theoretical Seminar: seminar participation in theoretical problems, projects and presentations.
